It was very exciting to head last week to record the audio version of PUSH (release date 2/3/26 - pre-order link in bio).
Not only did I get to hold a proof copy, which is always a thrill, but for the first time, I was able to record an audiobook telling the story of motivation and why it’s so important for healthy longevity.
The book is all about ways to evaluate and maximize your motivation, how to learn to push yourself for mental, physical, and physiologic benefits.
I’ve highlighted many of the incredible patients I’ve had the honor of taking care of, their motivational stories, and how to use some of these lessons for yourself.
I look forward to sharing this message in the year ahead!

Instagram Life vs. Real Life - New York City Marathon Edition.

Yesterday I was honored to participate in the largest marathon ever, joining 59, 225 fellow runners who completed the 26.2 mile distance at the TCS New York City Marathon.
Looking at the smiling photos that many posted, it might look like running a marathon is only about enjoyment. The truth of the matter is that there are times along the way where you want to quit, you probably want to puke, and for sure you want to walk.
Somewhere inside, you find the strength to push ahead, whether you’re the first finisher or the last.
These two pics from my day yesterday, the smiling fake-news photo at the end and the more realistic, please get me up this damn 59th street bridge photo, are both part of the tidal wave of emotion that make this event so incredible.
Most of all, the more than 1 million fans along the way, and many thousands of volunteers, help every runner find the courage inside themselves to push ahead and dig deeper inside than they realized was possible.
Running a marathon is a triumph of the human spirit.
Thank you everyone who helped us all get to the finish line. 🙏🏻🙏🏻

As we learn more about the importance of building and maintaining skeletal muscle mass across the lifespan, we’re learning more about myokines which are secreted by skeletal muscle during activity. This is true for all types of activity, but especially within tense activities like HIIT training.

Myokines have anti-inflammatory effects across multiple body systems, changing the risk of chronic disease in organs including heart, brain, intestines, and lungs.

The message here is clear, keep your muscles strong across your lifespan not only to help you move better, but also to reduce the risk of chronic disease and keep you healthy. Most importantly, PUSH yourself every chance you get! Your future self will thank you

The article below gives more information about the importance of muscle for overall health.

It was an honor to speak at Boston today on the subject of fitness motivation as determinant of healthy longevity.

I shared how our IronStrength community has helped me develop the tools to motivate others through community, fun, and muscles. The holy Grail of the exercise prescription is compliance.

Dear Friends,

I am extremely pleased to announce that my newest book PUSH: Unlock the Science of Fitness Motivation to Embrace Health and Longevity, will launch on Feb 3, 2026 (pre-order link in bio). The book (and audio book) is my fifth in a series bridging the worlds of medicine and fitness to help people learn to live healthier and more active lives. It will be published by Penguin Random House.

PUSH is the result of several years of research, patient interviews, and analysis of the science of fitness motivation. It’s a murky topic that’s difficult to understand - what makes and keeps people motivated across their lifespan.

Having cared for many thousands of active patients over my career as a sports medicine physician, having led many thousands of people in fitness events in our IronStrength community, and having run, biked, swam and limped over many thousands of miles in my athletic career, I have written this book to try and answer the basic question WHY?

Why do some people keep moving to maximize healthy longevity while others struggle? What lessons can we learn to try and motivate and inspire others to continue moving? What tools can people use to analyze and improve their own fitness motivation?

Most importantly, why should you learn to PUSH yourself, both mentally and physically, to maximize your own musculoskeletal and physiological health?

I look forward to sharing this information in the months ahead and to the book launch events and lectures in 2026!

In the meantime, please feel free to join my mother and pre-order the book (if you’d like)! I look forward to seeing you on the road soon.

It was an honor to present the Miles of Impact award this weekend on behalf of HSS the New York Road Runners Club at the conclusion of Gretta’s Gallup 10k race in Central Park.
The award is presented to a member of the community who is making an impact through a combination of innovation, integrity, and teamwork.
This year‘s winner, Julia Ancona, started a community running program in Brooklyn and regularly gets her community out and moving.
It is a pleasure to celebrate people who are making a difference. Now more than ever, community is a way to work together to uplift us all.

After seven years away it was an honor to fire-up the tiger suit and participate in the in Lake Placid yesterday. The full Ironman distance, 2.4 mile swim, 112 mile bike, and then a 26.2 mile marathon tests every part of your physical and mental being.

I used to take for granted that I would finish one of these every year, but during torrential rains, baking heat, and all kinds of other difficulties along the way, I had to keep pushing the voices of “let’s stop right here” away.

For me, this day was especially emotional because my dearest dad was an Ironman super fan. He would sit outside on the corner in Lake Placid all day, from morning to night, just waiting to see his boys go by. I thought of him often and missed him yesterday.

I am especially grateful to the incredible volunteers of all ages, grandparents, parents, and kids, who manned aid stations in the worst possible conditions, pouring rain, baking heat, with smiles and enthusiasm and cheers Thank you! You help keep us going, even when we wanted to stop.

I’m also very appreciative of friends and family who tracked me throughout the day, watching my small dot on the map progress from place to place as I kept moving ahead. Thank you so much for your notes and texts and supportive comments, all of which I got at the end when I turned on my phone.!

Congratulations to all the participants who completed this somewhat crazy event yesterday, and special shout out to my race buddies and ! Great job!!

In life, it is important to give goals that are scary and push you outside of your comfort zone. It is what makes us all strive to reach new heights.

With a profound sense of gratitude, I’m off to eat a big hamburger.

Do stronger glute muscles decrease the risk of injury for runners?

I’ve had a fifteen-year obsession with strength, and for runners in particular, the importance of gluteal strength. When we started with IronStrength 15r years ago, the goal was performance. Plyometrics meant stronger muscles, improved running economy, and improved power output. Over time, I began prescribing plyometric-based strength for my patients with similar results for them as well.

Over the years, the incorporation of strength into my sports medicine practice has evolved, initially from performance now to prevention.

As such, it was an honor to be part of a study published last week (link below) led by the amazing and our running medicine collaboration with and .

The study sought to ascertain if stronger glute muscles, assessed using a single-leg glute bridge, reduced the likelihood of running related injury.

The answer - YES IT DOES! By 49%!

In short, what I’ve been saying for years, = is scientifically valid.

Summary: Get out there, lunge, squat, deadlift, and build those glutes to stay on the road and out of the office.

It was an honor to meet this morning with fitness/health icon and founder Nerio Alessandri. Starting in his garage with a concept of functional fitness in the 1980’s, he built Technogym one of the world’s most innovative fitness and wellness companies.

We discussed our mutual commitment to expanding the usage and messaging of exercise for preventive health and discussed ways to bring the domains of medicine and movement closer together for the benefit of all.

it is always such a pleasure to meet a kindred spirit who is equally committed to preventive health through movement. He is an inspirational human being.

Doctors Lounge Circa 2025:

Last year embarked on a project to create one of the first wellness spaces for our health care professionals. The concept is that healthcare professionals spend their careers taking care of others, while sometimes neglecting their own physical and mental health.

The Halvorsen Wellness Center, a state of the art facility open to everyone at HSS, is designed to address these issues.

With spaces for mental health, physical health, and recovery, the goal is to provide a place where those who take care of others, nurses, physical therapists, physicians, medical staff, administrators, physician assistants, researchers, and everyone who helps make HSS exist, can work together to create a healthy community.

In this morning’s strength class we had a great group from across the institution, it’s like that every time. All classes are free, all you have to do is register and show up!

The hope is that our employees will continue to utilize this space, and that other institutions will see this as a model and create similar locations for their own staff.

In the old days, it was coffee and donuts in a doctor’s lounge. Today it’s working hard in a group fitness class to build fitness, muscle, and camaraderie. Great job everyone! Looking forward to seeing you in our next class 💪🏻💪🏻
